Application filed April 22, 1908. Serial No. 4.28.543.

To all whom it may concern:

Be it known that we, THOMAS H. BUTLER, residing at Baltimore city, Maryland, and FRANCIS M. WIDERMAN, residing at New York city, in the State of New Yorlg have invented certain new and useful Improvements in Corn-Huskers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

This invention relates to machines for husking corn; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of the machine. Fig. '2 is a plan view same. Fig. 3 is "a longitudinal section through the machine, taken on the line roc in Fig. 2. Fig. 4 is a cross-section through the husking-rolls, drawnto a larger scale. Fig. 5 is a longitudinal section through a portion of the smooth husking-roll. Fig. 6 is a detail longitudinal section through ortions of the cylinder, disks, nuts and was ers used in forming the smooth husking-roll, showing the parts before being screwed up A is the frame of themachine, and B is the driving-shaft .journaled in the lower part of the frame and provided with any approved form of driving-wheel l). I

O and D are the two husking-rolls. The roll 0 is secured on a shaft 0, and the roll D is secured on the shaftcl, and these shafts are mounted to revolve in the frame A in any approved manner, A. toothed wheelie is secured on the shaft 0 and gears into a toothed wheel d secured onthe shaft (1 so that the rolls revolve in opposite directions. The two rolls are driven by a toothed wheel I) secured on the shaft B and-gearing into the wheel 0. r 5

The roll 0 is preferably provided with. a series of spikes 2 arranged in s iral form. Sockets 3 are let into holes or poc rets in the roll, and the spikes project through holes in guide-plates 4 secured at the topsof the sockets. The spikes have heads 5 inside the *socketsfand 6 are spiral springs arranged between thesaid'g heads and'the bottoms of the sockets. Instead of having spikes, the roll C may have any other approved'form of projections for giving it an'uneven surface which will remove the husks from the corn.

The roll D is providedwith a surface of soft of the or pliable material. The .body portion 7 of the roll is screwthreaded, and is provided with longitudinal grooves" 8. Washers having tapering edges are slid loosely upon the part 7 and are provided with projections or splines 10 which engage with the grooves 8 so that the washers do not revolve on the part7. Nut washers 1.1 are screwed at intere valsupon the body part? of the roll, and have thin facing washers 12 upon one side of them. Disks 13 of soft material,-such as an. india rubber composition, are arrangedbetweenthe washers so as to form an unbroken cylindrical surface at the periphery of the roll. The nut-washers 11 together with the screwthreaded portion of the roll constitute means for compressing the disks 13 betweenth'e washers 9, and they also operate as fasteningdevices for clamping. the said disks and washers on the body portion of the roll. The washers have holes 14 or other equivalent means for engaging with the sides of the disks 13, so that the said disks are gri ped tightly when the nut washers are screwe up. When holes 14 are 1 provided the soft material of the disks 13 is squeezed slightly into the endportions of the holes by the end pressure of the nut-washers when screwed up. The disks 13 are of larger diameter than the said washers, and their peripheral portions are pressed over the edges of the washers so that the roll has a continuous yielding surface. The sides of the disks are recessed to receive the washers as much as desirable according to the thickness of the washers used; Any part of the periphery of the roller can be renewed when it becomes worn by contact with the projections of the rolls G 01 with the ears of corn.

E is an endless apron of flexible material carried by rollers F and G. The roller F is secured on a shaft f which is journaled in the frame A at the front end of the machine. sprocket-wheel f is secured on the shaft f, and eis a drive-chain which passes over the sprocket-wheel f and over .a sprocket-wheel e secured on the driving-shaft B. The roller G is arranged at the rear end of the machine, and is secured on a shaft 9 which is journaled in slidable bearings g. The bearings gslide horizontally in guide-slots. it formed in the frame A, and H are springs which press the the apron E bearings g rearwardly and hold under aprearranged tension. 1

I isthe pressing-roll which bears on the middle part of the lower E, and which is arranged over the spiked husking-roll C, This roll I is a shaft *5, the end portions of which slide up and down in guide-slots i in the frame ,A.

J is an endless conveyer-carrier of flexible material. The rearend of this carrier passes over a roller K which is secured on a shaft 7:. The shaft k is journaled in the frame A, and has a toothed wheel k secured on it, which gears into thetoothed wheel I). The car rier J is arranged at an angle with the horizontal, and a converging passage j is formed between its upper bight and the front end portion of the lower bight of the apron E. The said bights are driven positively, at the same speed and in the same direction. The front end of the conveyerecarrier J over a roller L which is secured on a shaft j. The shaft y" is journaled in the lower ends of links M which are pivoted to-the frame A by pins m. The frame A is provided with slots or openings which permit the shaft y" to -be moved by the links to adjust the :tension of :the carrier J, and m are clampingscrews for securing the said links to the frame in any desired position.

' N is the upper :end portion of a feed elevatorof any approvedconstruction. This elevator is driven by a drum at having a driving-sha ft n which is journaled in the frame A. This shaft 01- is driven by a drivechain 0 which passes over a sprocket-wheel 0 secured on the shaft or, and over asprocke-twheelo secured on the shaft 7c.

is a curved guard-plate secured to the frame A over the upper end of the elevator.

S is a finger pivoted to an arm 8 which is secured to the frame A. The finger S projects over the elevator buckets or slats and arranges any car of corn in position which may be projecting in an undesirable manner.

The ears of corn are fed into the elevator, and are carried up and are discharged one by one at periodic intervals into the larger end of the converging passage y. The cars of cor-n are grasped between the two opposed bights which form the said passage 7, and they are pressed upon the spiked huskingroll 0 by the pressing-roll I. removed "by the joint action of the rolls C and D and the lower bight of the apron E. The husks fall between the rolls C and D, and the husked ears slide down chute T into a suitable receptacle. A cleaning-roll is secured on the shaft B and is of any approved construction. This cleaning-roll prevents the husks from adhering to the spiked husking-roll C. This cleaning roll is not shown in the drawings as its use may be disoensed with, if desired, or any other approved cleaning device may be used in place of it.
